## Abstract

EPA is finalizing a limited approval and limited disapproval of revisions to the Bay Area Air Quality Management District (BAAQMD) portion of the California State Implementation Plan (SIP). This action was proposed in the Federal Register on July 24, 1997 and concerns oxides of nitrogen ( NO<INF>X</INF>) and carbon monoxide (CO) emissions from boilers, steam generators and process heaters in petroleum refineries. Under authority of the Clean Air Act as amended in 1990 (CAA or the Act), this action simultaneously approves a local rule that regulates these emission sources and directs California to correct rule deficiencies.
